xClassification Trees

xClassification Trees are defined in two pieces. The standard form defines basics such as the name and identifying number of the tree as well as two additional configurations:

• Restrict Selection To Only Leaf Classes

When selected, you can only select leaf classes in the xClassification Tree. These are classes that have no child classes.

• Restrict Selection To A Single Class

When selected, you can only choose one Extended Classification for each Item. Disabling this flag allows you to assign multiple xClasses to a single Item so that all of those xClasses properties are available.

The relationship tab “Item Types” defines the ItemTypes where this extended classification tree is available.

To define the xClassification Tree, select the Show Editor icon in the green sidebar. This displays an Editor that enables you to perform the following functions:

• Create the Tree structure- To add a new xClass, right click on the top level of the tree and select Insert Sub-class. The top level xClass shares the name of the xClassification Tree.
• Assign xProperties to specific xClasses – Select the xClass from the tree in the left column and select Pick Related from the dropdown list in the toolbar on the right. Click the New Relationship icon . The xProperty search dialog opens, enabling you to select the desired xProperty. An xClass can have multiple xProperties assigned to it.

Figure 6.

In this xClassification Tree seven xProperties are assigned to various xClasses. When you select a node, all included xProperties appear in the right grid. Those with a grey background are inherited from higher level xClasses. The xProperties defined for the selected xClass appear with a white background.

• Within the grid, it is possible to drag and drop rows by clicking the in a particular row to reorder the xProperties. The order shown will be the same as the order that appears on an Item’s form when you select the xClass to classify the item. You can also use the Move Up and Move Down buttons in the Editor Toolbar to reorder rows.
